Hi Yorkie,
Holding a unit up to the light can provide an unrealistic view of a hair piece. Even a dense piece with back lighting will not block all the light---only a piece with extremely heavy density that has hair knotted next to knotted hair will block all the light. And that would be a very unusual piece. When you look at the photos of the unit without product it looks realistic. I agree with SilverStreak. This is your first unit and it makes an easy transition to wearing--the change is more subtle than a heavier unit. You can dial up the density on your next order if you like. Just my two cents. Of course you can return it to me to have hair added if you like.
Regards,
John
